Patent DE-4205084-A1 (DE)
Title: Electromagnetic radiation receiver e.g. for antitheft security systems - consists of adjacent pairs of  conductors in common planes, each pair wound into octagonal coils with equal numbers of turns and density
IPC: H01Q1/36
Filed: 1992-02-17
Abstract: Device has as least one pair of conductors in the form of flat spirals with approx. equal numbers of turns and winding density, and these spirals are close together in one common plane. The windings are preferably mounted on epoxy resin. The simple example shown has two spiral windings (1,2) mounted on a plate (3); each winding is octagonal, the one (1) starting with a straight length (4) from a contact (5) and passing spirally inwards clockwise to a central through-contact (10). Here it meets the inner end of the next conductor beneath, from which it turns in the same winding direction outwards. Its outer end then comes to another through-contact to meet the outer end of the next conductor beneath. From there it passes again along a winding etc.. The conductor (2) is similar except that its initial straight length (7) leads to a winding in the anti-clockwise direction. The terminals (5,5') are connected to a suitable supply. The conductors are e.g. copper wound with 127 microns between turns. ADVANTAGE - The antennae concerned suppress interfering signals to a very high degree.

Title: Automatic system for identifying data of individual tyres
Inventor: SEEWE KLAUS G
IPC: B60C13/00
Filed: 1992-12-18
Abstract: A method identifies individual tyres which have various different properties, e.g. different dimensions, cross-sectional shapes or profiles, carcass constructions and/or types. The tyres are given a marking which has the details concerned and which is read off during or before the tyres are handled in (in particular) quality control, storage, stacking or transporting. The details of the marking are stored in at least one data carrier and are transmitted to a receiver in the form of electromagnetic signals.The example shown has a data carrier (4) in a tyre (2) and a receiver (6) for a signal emanating from the carrier (4), which is a transponder (8) with a data store and aerial built in. The microchip to store data holds details of the dimensions and profile of the tyre etc. The receivers (6) are located under the plane (4) in which the tyres are moved; they have the corresponding decoders and transmitters directing low frequency radio waves upwards. When a transponder (8) enters the electromagnetic field of a receiver (6) it takes energy from the induced current. The effect is to convert generated signals in the decoder to suitable action in the quality control system.

Title: Method and inverter for the conversion of direct current into three-phase current
Inventor: KLEINKAUF WERNER PROF DR ING
IPC: G05F1/67
Filed: 1993-02-01
Abstract: Energy conditioning method is proposed which forms a three-phase system by the production and distribution of modulated or unmodulated voltage pulses from a DC voltage. The DC voltage is converted by means of a push-pull circuit or bridge circuit (12, 13, 14, 15) into a high-frequency alternating pulse train, which is transformed with the aid of a transformer (5). On the secondary side, the pulses are split by means of AC semiconductor switches (16, 17, 18) which are arranged in a star circuit or bridge circuit, directly into three different phases in accordance with a specific pattern, so that a balanced three-phase system is produced. This method enables a virtually continuous energy flow from the direct-current side via the transformer to the three-phase current side (Fig. 2). <IMAGE>

Title: Method for data exchange between data processing equipment and the control system of exchange equipment
Inventor: BERNHARD REINER
IPC: H04Q11/04
Filed: 1993-05-29
Abstract: It is to be possible for the purpose of exchanging data between data processing equipment and the control system of exchange equipment to operate the data processing equipment at an arbitrary digital base terminal which may also be situated outside the exchange equipment. The measures required for data exchange in the exchange equipment are to require only little preliminary work. Provided for this purpose is a special digital user-network interface which can be driven via a subscriber number (call number) from the data processing equipment. This user-network interface is assigned a B-channel control system, which is used to form packets from the data incoming on the B-channel or the B-channels which pass onto a bus system internal to the equipment. From there these data pass to the respectively addressed central or decentral control system. In the reverse direction, acknowledgements (responses) or response messages pass via the same path to the data processing equipment. The data processing equipment can be connected at an arbitrary location inside or outside the exchange equipment so that data can also be exchanged using a connection established (set up) via the public network (public telecommunications network). Those parts of the exchange equipment with which data are to be exchanged are driven directly by addressing.

Title: Device for receiving a card-shaped data carrier on a coin channel designed in the manner of a rectangular tube
IPC: G07F7/00
Filed: 1993-06-01
Abstract: For receiving coinage, coin-operated self-service machines have at the front a coin-insertion slot followed by a coin channel which terminates at a coin tester. The innovation on which the invention is based is now to afford the possibility that self-service machines can be operated both with coinage and with a credit card. To receive a data carrier designed as a credit card, the coin channel has guide grooves, in which the data carrier can be introduced into the coin channel. Arranged on the outside of the side wall of the coin channel is a contact unit which projects through perforations into the coin channel. As a result of the introduction of the data carrier, the latter butts against a stop tab of a frame part of the contact unit, with the result that the latter is deflected in the direction of the data carrier.

Title: Calorimeter for precise measurement of temperature signals in liquid phases
Inventor: ANDERSON HEINZ PROF DR RER NAT
IPC: G01K17/00
Filed: 1993-06-30
Abstract: Calorimeters are used for measuring quantities of heat in physical, chemical and biological reactions/processes. The main problem of the isoperibol technique most frequently used consists in guaranteeing constant temperature of the enclosing thermostat. This requirement can be satisfied only if a homogeneous temperature field can be provided. The object of the invention is to monitor physical, chemical and biological processes which take place in reactors, by means of their temperature signals, and at the same time to guarantee a high homogeneity both of the temperature of the thermostat and also of the temperature and the concentration in the reactor. This object is achieved by virtue of a calorimeter, in the liquid thermostat of which at least one reactor and at least one precision burette pump assigned to this reactor are arranged, the reactor communicating with the precision burette pump for introducing a process component into the reactor via an inlet tube, and the reactor being equipped with means for homogenising the reactor content, with means for detecting the temperature signals and with means for taking calibration measurements and for inputting defined heat quantities into the reactor, and the liquid thermostat having means for homogenising the temperature of the thermostat liquid.

Title: Process for recovering metals from an acid-containing metal salt solution
Inventor: FROEHLICH SIEGMUND DIPL CHEM D
IPC: H01M6/52
Filed: 1993-09-01
Abstract: The invention relates to a process for recovering metals and/or basic materials of chemistry from an acid-containing metal salt solution, in particular in the reprocessing of used domestic and portable batteries, in which the individual metals are first extracted one after the other in ion exchangers, then eluted by acid and finally regenerated for example by subsequent electrolysis and/or other process steps. In order to enable eluate fortification or the increase of the metal concentration without an additional concentration operation and without special energy expenditure and thus economically, the metal separated off in the ion exchanger is first substantially flushed out in a first process step using an eluate acid which was temporarily stored after a preceding elution operation and then, in a second process step, the ion exchanger is washed with fresh acid and this eluate acid is temporarily stored for the first process step of the next elution operation. <IMAGE>
